. Key words: Al-Mg alloys; superplasticity; solute-drag creep; tensile ductility; strain-rate sensitivity ... is the absolute temperature. For 5000-series Al-Mg alloys, enhanced ductilities during high-temperature creep deformation can be achieved from either fine grained superplasticity or solute-drag creep. Fine......
at lower temperatures. Aluminum-magnesium alloys could potentially be used as hydrogen storage materials. A novel method for Al-Mg deposition was proposed by using pure Mg anodes in the organic solvents system benzene-tetrahydrofuran-AlCl3-LiAlH4. XRD shows that the aluminum-magnesium alloys are mainly Al3Mg2 and Al12Mg17.Key words:electrodeposition; aluminum coating; aluminum-magnesium (Al-Mg) coating......

:常压下枝晶间大量存在的Al3Mg2相在高压凝固时消失,形成另一密排六方结构相；经300 ℃, 11 h时效处理后,组织变得不稳定,六方结构相消失,转变成稳定的Al3Mg2相,但其形态由常压下三岔分界形式转变成团状,由此推断该六方结构相为亚稳相；在高压凝固条件下Mg在Al基体中的固溶度由7.74%增大到11.3%,Al相的晶格常数增加, 在XRD图中表现为Al相衍射峰左移,但经时效处理后,Al相衍射峰基体又回复到常压时的位置. 关键词:高压凝固组织；Al-Mg合金；时效处理 中图分类号:TG 113.12；TG 146.2 文献标识码:A High pressure solidification microstructure and stability of Al-9.6%Mg alloy WANG Zhen......
